AC 28 Skylight Roof cut fill default can't be changed

[Brad Elliott]

I have a project that has been brought up from AC 26. I have added a skylight to the roof and am getting a brick pattern in the roof cut. I have tried various materials as well a basic and composite structures but still have the same pattern.

If I turn the lining off it shows up clearly in he 3d model which I have attached. I tried turning the lining on as a work around and it covers in the 3d view but the brick pattern still shows up in sections and elevations.

How do I change or hide this pattern?
